6* Suppose
it was possible to create an electric car that was safe, fast, and inexpensive.
Would auto companies invest the money to make it or would government subsidies
be required?

7* If
consumers were interested in buying a lot of electric cars, would gas stations
and other outlets open charging stations for the cars? Or, would the government
have to set up charging stations around the country?

8* Looking ahead a
decade, how likely is it that most cars will still run primarily on gasoline?

9* When a
replacement for gas powered cars is eventually developed, is it more likely to
be developed by private companies hoping to make a profit or by government
subsidies and investments?
